Shale having kerogen deposits therein is exposed to a liquid carrier medium such as water or distillate. High level vibratory energy is applied to the kerogen carrying shale and the liquid to cause the oil shale to comminute so as to release the kerogen therefrom, the kerogen itself being comminuted and suspended in the carrier liquid, which liquid is then removed and the oil separated therefrom.
